[PATCH 0/2] hw/arm: Fix STM32L4x5 EXTI to CPU irq fan-in connections

[Inès Varhol]

The original code was connecting several outbounds qemu_irqs to the
same qemu_irq without using a TYPE_OR_IRQ.

This patch fixes the issue by using OR gates when necessary (1st commit).

I attempted to check that the problem is fixed by using a QTest (2nd commit)
but actually the test is passing even before the fix :
when any fan-in input line is raised, the output is raised too.
